The cabinet it)‘ is divided by a lateral partition 25 into
upper and lower portions,’ the lower portions serving as
a reservoir for ?uid, and suitable drains 26, preferably
having perforated‘ covers 27,, are provided to drain ?uid
from the upper into the lower cabinet. A drain valve

Bearings, particularly expensive precision bearings such
its way into bearings, causing ultimate failure and dam
age, represent a considerable factor in costs. Hand clean
ing, as heretofore used, is unsatisfactory, and various
cleaning apparatus heretofore have generally proven to
be either unreliable and/or expensive, as well as often
being inconvenient to use.
‘An object of the present invention is to insure elimi
nation of foreign matter from bearings by providing a
simpli?ed and reliable cleaning apparatus.
Another object of the invention is to increase bearing
life by providing an improved bearing cleaning and treat
ing apparatus.

sizes of bearings 34 as illustrated by the dotted. lines of
FIG. 4. It will be seen thatv the cone shape of member
32 also ensures centering of the bearing 34.
Oil is the preferred ?uid used for cleaning and treat
ing theybearings 34, and a su?icient supply is maintained
within the lower portion of the cabinet 10. The cabinet
10 is provided with an outlet 35 connected by a pipe 36
to a ?lter 37 which is connected by a pipe 38 to the intake

a pipe 4-1 to an. inlet 4-2 of the cabinet 11). A pressure
